Bottom-trawling fisheries influence on standing stocks, composition, diversity ...
Ramalho, Sofia P.; Almeida, Mariana; Esquete, Patricia; Génio, Luciana; Ravara, Ascensão; Rodrigues, Clara F.; Lampadariou, Nikolaos; Vanreusel, AnnBottom-trawling fisheries operating in Portugal (West Iberian Margin) impose one of the largest footprints per unit of biomass landed in European waters at depths greater than 200 m, affecting the seafloor integrity and the associated benthic fauna. To investigate how trawling pressure is affecting the macrofaunal assemblages, we compared the standing stock (abundance and biomass), community structure and taxon...
Resilience of benthic deep-sea fauna to mining activities
Gollner, Sabine; Kaiser, Stefanie; Menzel, Lena; Jones, Daniel O.B.; Brown, Alastair; Mestre, Nelia C.; van Oevelen, Dick; Menot, Lenaick; Colaço, AnaWith increasing demand for mineral resources, extraction of polymetallic sulphides at hydrothermal vents, cobalt-rich ferromanganese crusts at seamounts, and polymetallic nodules on abyssal plains may be imminent. Here, we shortly introduce ecosystem characteristics of mining areas, report on recent mining developments, and identify potential stress and disturbances created by mining. We analyze species' potent...

Identifying toxic impacts of metals potentially released during deep-sea mining...
Hauton, Chris; Brown, Alastair; Thatje, Sven; Mestre, Nélia; Bebianno, Maria; Martins, Inês; Bettencourt, Raul; Canals, Miquel; Sanchez-Vidal, AnnaIn January 2017, the International Seabed Authority released a discussion paper on the development of Environmental Regulations for deep-sea mining (DSM) within the Area Beyond National Jurisdiction (the “Area”). With the release of this paper, the prospect for commercial mining in the Area within the next decade has become very real. Moreover, within nations’ Exclusive Economic Zones, the exploitation of deep-...
Submarine and deep-sea mine tailing placements: a review of current practices, ...
Ramirez-Llodra, Eva; Trannum, Hilde C.; Evenset, Anita; Levin, Lisa A.; Andersson, Malin; Finne, Tor Erik; Hilario, Ana; Flem, BelindaThe mining sector is growing in parallel with societal demands for minerals. One of the most important environmental issues and economic burdens of industrial mining on land is the safe storage of the vast amounts of waste produced. Traditionally, tailings have been stored in land dams, but the lack of land availability, potential risk of dam failure and topography in coastal areas in certain countries results ...
The influence of geological, geochemical, and biogenic habitat heterogeneity on...
Cordes, Erik E.; Cunha, Marina R.; Galeron, Joelle; Mora, Camilo; Olu-Le Roy, Karine; Sibuet, Myriam; Van Gaever, Saskia; Vanreusel, Ann; Levin, Lisa A.Cold seeps are among the most heterogeneous of all continental margin habitats. Abiotic Sources of heterogeneity in these systems include local variability in fluid flow, geochemistry, and substrate type, which give rise to different sets of microbial communities, microbial symbiont-bearing foundation species, and associated heterotrophic species. Biogenic habitats created by microbial mats and the symbiotic sp...
